Explanation:

Peter the Great expanded and formalized serfdom, tying serfs more tightly to landowners and expanding the categories of people subjected to serfdom, worsening their conditions. Nicholas II ruled during the final years of serfdom (which was abolished in 1861, before his reign) and focused on other late imperial issues. Alexander II is known for abolishing serfdom in 1861, improving the status of serfs.

Peter the Great
